Flanged dredging HDPE pipe with stub end for river dredging fine
sand introduction
As dredging becomes more & Most popular today, HDPE pipes used
to be the ideal option for transporting pressurized liquids
containing a mixture of water and inerts such as clay, silt, sand,
gravel and bulky solids. HDPE dredge pipes are made of high-density
polyethylene and can be manufactured in a variety of sizes. The
dredger pipes are manufactured and welded with two HDPE flange
adapters and two steel flanges, also called "HDPE flanged pipes",
, the two pipes of which can be easily connected together by
flanges and covered with floats to float over sea dredged pipes,
which is preferred for agricultural applications, mud dredging,
mining projects. HDPE dredge pipes are used with polyurethane
(foam) filled floats.Some models are to be used with rubber hoses
for river or sea dredging.
